Step-by-Step Instructions
Follow these steps carefully
1
Set up at the passenger side of the Avenger
Every 2008–2014 Avenger hides its cabin filter behind the passenger-side glove box. Park, shut it off, open the door. Empty the glove box fully — it must swing all the way down — and light the footwell so the housing tabs are easy to see.
🔧 Mechanic's note — Tom Becker
Learn from my mess: empty that glove box before you drop it, or you'll be fishing registration papers and loose change out of the footwell.
2
Drop the glove box by squeezing both sides
Push both side walls inward together so the stop tabs clear the dash, then swing the box down on its hinges — no tools, a few minutes. If it hangs crooked, one side hasn't cleared; press that side in again, don't yank.
3
Unclip the filter housing cover
Pinch the squeeze tabs and pull the cover straight toward you — by hand, no screws. Photograph the old element and its airflow arrow first; that arrow direction must be replicated. Set the cover where it can't fall behind the dash.
🔧 Mechanic's note — Ray Delgado
My rule: That photo is worth it — the arrow direction is the one detail you can't guess later, and flipping the filter starves airflow.
4
Slide out the old filter and read its arrow
Pull the old filter out and check its airflow arrow first — the new one goes in the same direction. Compare old and new side by side; the correct element fills the housing with no edge gaps.
5
Clear the housing and inspect while it is open
With the filter out, look into the empty housing for leaves, dust mats, or foam crumbs and pick them out by hand or with a vacuum nozzle — do not shove debris deeper toward the blower motor. Wipe the cover's sealing edge with a dry cloth so the new filter seats against a clean rim. Check the housing walls for cracks, which are uncommon but worth a glance on a 2008–2010 car. This is also the moment to sniff: a musty smell in the empty housing usually means the old filter was long overdue, and the fresh element will fix it.
6
Seat the new filter and lock the cover with a click
Slide the new filter into the housing with its airflow arrow matching the old one's direction, pushing it fully home so it lies flat with no curled corners. Press the cover back on until you hear and feel it click into place — the Avenger's cover must latch positively, and a cover that is merely resting in place will whistle at high fan speed. Tug it lightly to confirm both tabs caught. Then lift the glove box back up past its side stops until it clicks into the dash and close it.
7
Verify the HVAC and note the interval
Start the car and run the blower from low to max on fresh-air mode. Airflow at the dash vents should feel strong and clean, with no whistling behind the glove box — any whistle means the cover is not fully clicked in. Run the A/C for a few minutes to confirm the stale or musty smell is gone. Plan on checking this filter every 12,000–15,000 miles or once a year; Avengers that do a lot of city driving clog theirs faster. If airflow stays weak with a new filter in place, the restriction is elsewhere — cowl intake or blower — not the element.
🔧 Mechanic's note — Ray Delgado
I never skip this: Still weak airflow with a new filter? Nine times out of ten the cowl intake is packed with leaves — clear it before you blame the blower motor.
All Done!
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
⚠️ Common Mistakes to Avoid
- • Resting the filter cover back in place without latching it — it must click, or it whistles and leaks unfiltered air.
- • Installing the new filter with the airflow arrow reversed; always match the old element's arrow.
- • Forcing the glove box down without squeezing both sides past the stops, snapping the plastic stop tabs.
- • Assuming the car never had a filter because the slot is empty — some Avengers shipped that way, and the slot is meant to be filled.
